Specification of Letters Patent.

Application filed July 15, 1904. Serial No. 216,735.

I To all whom it may concern:

Be it known that I, WILLIAM H. J AoKsoN, a citizen of the United States,residing at Bakersfield, in the county of Kern and State of California,have invented a new and useful Spring-Spoke for Vehicle-Wheels, of whichthe following is a specification.

This invention relates generally to vehiclewheels, and more particularlyto the construction and arrangement of a spring-spoke forming a partthereof and by means of which a certain amount of yielding motion orelasticity is obtained between the rim and hub and by means of which acushioned tire is made to ride aseasy as a pneumatic tire.

The invention consists in the novel features of construction andcombination of parts hereinafter fully described, and pointed out in theclaims.

In the drawings forming a part of this specification, Figure 1 is adetail elevation, partly in section and disclosing all the features ofmy invention. Fig.' 2 is a detail view of one of the spokes, the rim andtire being shown in section and the hub in elevation. Fig. 3

- is a detail perspective view of one of the tubular sections of thespoke. Fig. A is a detail perspective view of the protecting-sleeve, andFig. 5 is a detail perspective view showing the solid portion of thespoke and the adjacent portion of the rim and tire. Fig. 6 is a detailview of the spring.

In carrying out my invention I employ an ordinary hub A, to which thetubular spokesection B is attached, the inner end of said spoke-sectionbeing threaded, as shown at B, and screwed into the hub.

C indicates a flexible metal rim having the outwardly-extending grippingmembers C, which are adapted to grasp and hold the cushion-tire D,preferably of rubber.

E indicates the solid spoke-section, which is rigidly connected to therim C and has a threaded head E at the juncture of the rim and spoke.The solid spoke sections are adapted to fit into the tubularspoke-sections, as most clearly shown in Fig. 2, and a coilspring Fsurrounds the solid portion E and the outer portion of the tubularsection B, said spring bearing at its outer end against the threadedhead E and at its inner end against the collar B arranged upon thetubular section B, and the joint between spoke-sections and the springare enveloped by means ofa sleeve G, threaded at its upper end, as shownat Gr, and adapted to be attached to the threaded head E, said sleevehaving an opening G at its inner end through which the tubular section Bpasses.

By means of the construction herein shown and described it is obviousthat there will be a limited amount of yielding movement or elasticitybetween the rim and hub, as the solid section of the spoke willtelescope or slide into the hollow section and the spring F will take upthe strain, the sleeve sliding upon the tubular spoke-section at thesame time the solid spoke-section slides therein. This sleeve thoroughlyprotects the operative parts and prevents the accumulation of dust,dirt, snow, or ice interfering with the operation of the device.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A wheel comprising a hub, radial tubu-v lar spokes carried by thehub, a rim, spokes carried by the rim and having their inner endportions loosely working in the tubular spokes, a coil-spring encirclingthe point of juncture of the hub and rim spokes, respectively, and asleeve inclosing the said spring.

2. A spring vehicle-wheel comprising the huband rim, and a series ofsectional telescopic spokes, each spoke consisting of a tubular sectionsecured to the hub, a solid section secured to the rim, and having athreaded head at its outer end, a collar arranged upon the tubularsection, a spiral spring surrounding the joint of the sections, andbearing against the collar and the threaded head, and the sleevethreaded at its outer end and adapted to be secured upon the threadedhead, said sleeve having an opening at its inner end through which thetubular section passes.

3. A spring Vehicle-wheel comprising in combination a hub, a rim havingoutwardlyprojecting members, a cushion-tire secured by said members, thetubularspoke-sections secured to the hub, and having collars, the solidspoke-sections secured to the rim, and pro. vided with threaded heads,the spiral springs surrounding the spoke-sections, between the heads andcollars, and the sleeves secured to the heads and enveloping thesprings, said sleeves having openings at their inner ends through Whichthe tubular spoke-sections pass,

all of said parts being constructed, arranged and adapted to operatesubstantially as shown and described.
